This invention relates to collar shaping machines and has for its object the provision of an improved device for shaping or rounding the top portion of a double fold collar.

Heretofore, it has been the general practice to employ means, for shaping the collar, which leave the collar too sharp edged and therefore uncomfortable to the neck.

Further it has been found that there was a tendency for the tie to be held too tightly within the fold and the object'of thepresent invention is to provide an improved machine for the beforementioned purpose whereby the said disadvantages are avoided and which shapes the collar quickly, with asuitably rounded top edge; Further the device as constructed according to the present invention is cheap to manufacture, economical in use and efiicient in action.

In order that my invention may be easily understood I append hereto three sheets of drawings in which Fig. 1 is a perspective view of one form of the device constructed according to the invention.

Fig. 2 is a diagrammatic plan view of the device shown in Fig. 1, showing the gearing and driving means for the spindles and shafts.

Fig. 3 is a detail view showing the resilient means for supporting the spindle carrying the grooved forming wheel.

Fig. 4: is a detail view showing, the resiliently supported bearing for the vertical shaft. 7 I

In the device as shown in Figs. 1 and 2, a rotating main spindle A (shown in Fig. 2) is arranged beneath a table B, said spindle A being driven by a belt C and wheel D and being controlled by means of a clutch D thrown into or out of engagement by means of a handle D On the main spindle A, is fixed a chain wheel A which drives by means of a chain A a second chain wheel, E fixed to the end of a second spindle E. Spindle E is resiliently supported in a bearing E the said bearing being endwise movable against the pressure of a spring E carried in the bearing housing E and bein adjustable endwise by means of a bolt 6 adapted to be secured in adjusted position by a lock nut-E The chain wheels A and E and the chain A are housed, in a suitable cover F. At the end of the spindle E, towards the centre of the table B, is fixed a close to it is a On the main spindle A beneath the table B is a bevel pinion K, which drives a vertical shaftL by means of a bevel wheel K fixed on the said shaft L, said shaft being supported resiliently in bearings M carried in a housing M fixed on the'table B. The

bearing M is endwise movable against the pressure of a spring M and is adjustable endwise by means of a bolt M acting against the end of the bearin M, said bolt being adapted to be secure rubber roller or rubber faced wheel N fixed on the end of'said shaft L in close proximity to the rail or support J, which passes partly around said rubber faced wheel N, as shown in'Fig. 2. Arranged outside the said rail J, and passing around said wheel N,

ard O, carrying vertical rotating rollers The grooved wheel" G is externally heated by means of a gas flame issuing from a pipe P, fixed tothe side of the cover F and curving round to a point to the side of the wheel G, as shown.

In using the machine, the gas issuing from pipe P is ignited and the machine set in motionc The collar H is then pushed over the rail J, and beneath the heated forming wheel G. The rotation of this wheel pushes the collaralong the rail J, the collar being shaped at the topedge while being passed beneath the wheel G, and when it comes into contact with the rubber faced wheel N, it is dragged along the rail and around the wheel, its movement being'assisted by the vertical rollers. 0 until it is eventually ejected from the machine at the point Q. The operation is then repeated and it has been found that the speed 'of the work is greatly increased and that the collar will be In a collar shaping machine, a rail forv supporting a collar, a. grooved wheel coin adjusted 'p0S1t10Iiby. a lock nut M.
